I am an assistant professor in the School of Computing Science at Simon Fraser University. I lead the Computational Photography Lab, where we focus on mid-level vision problems with applications to AI-assisted image editing and video production. We work in our computational photography studio, conducting research in an active production environment.

Our independent research is funded by Natural Sciences and Engineering Research Council of Canada, Canada Foundation of Innovation, and the British Columbia government, as well as Adobe Research and Meta Reality Labs through generous gifts. We are a part of the rich visual computing environment at SFU CS.

My doctoral research was on novel representations for images that allow easier analysis of photographs with applications to realistic image editing and movie post-production. I received my PhD degree in Computer Science from ETH Zurich under supervision of Marc Pollefeys. During my PhD, I spent a year at MIT CSAIL with Wojciech Matusik's group and 3 years at Disney Research Zurich.
